These three categories of service can help you evaluate your chemical-treatment suppliers’ performance
HP Automation Safety: How are you treating your condensate?—Part 1
Condensed steam, i.e., condensate, is valued for its heat contentand purity. To minimize operating costs, condensate should berecycled back to the boiler feedwater system. Equally important, itshould ..
HP Water Management: How corrosive is demineralized water?
In petrochemical facilities, the most common application of demineralized water is for makeup feed for high-pressure boilers. For example, ammonia, methanol and hydrogen are several processes that req..
HP Water Management: Oxidizing biocides: How about bromine?
Recent environmental restrictions on the usage of chlorine and new alkaline-based chemical treatment programs have increased the application of bromine-based biocides in industrial cooling systems. Fo..
HP Water Management: Oxidizing biocides: How about chlorine?
Chlorine is the most popular biocide for industrial cooling systems and is typically the most cost effective. Industrial chlorine usage has declined due to concerns about the production of toxic triha..
HP Water Management: Proper pH measurement
Proper pH measurement is critical to control corrosion and deposition in water systems. The parameter pH is defined as the opposite of the logarithm (base 10) of the concentration of hy..
HP Water Management: What are the guidelines for boiler feedwater, boiler water and steam quality?
Several industrial guidelines address the quality of boiler water and steam. These standards were developed to provide guidance to designers and operators of steam-generating equipment...
HP Water Management: Why automate chemical feed and control systems?
Due to advances in microprocessor technology, the opportunities for process automation have increased dramatically while costs have decreased. Numerous strategies are available to autom..
HP Water Management: Ammonia plant water management issues
For ammonia plants, a vital goal is extending time between turnarounds. Currently, runtimes range from one to four years. Yet, ammonia facilities have several waterside issues that can ..
HP Water Management: What do these corrosivity indices mean?
Industry has developed several semi-quantitative measures of the corrosive tendency of water. Corrosivity is the tendency to sustain anodic or cathodic chemical reactions. System design..
